Answer:
a) f(3) = -19
b) x = -2 (I assume you have to find x, but the question isn't very clear)
Step-by-step explanation:
a) f(3) = -4(3) - 7 = -12 - 7 = -19
b) Suppose f(x) = 1. Then 1 = -4x - 7, so -4x = 8, and thus x = -2

I need help I don't know what to do

Answer:
Step-by-step explanation:
so you understand what to do, or what they want you to figure out.
AD is an "arc length" . So they want to know the length, in degrees. along the circle , from A to D. Why didn't they just say so, huh. :D well, they kinda did, but not as clear as they could have.
next. you need to know how far around a circle is all the way around?
if you guessed 360°, you are right
next because they gave us that angle of 93° we know all the angles around the point E, complimentary angles add to 180 so 180-93 = 87°. That's the to the left of 93 and directly below it too. This is the answer to the 2nd question ∠DEC= 87°
we can only write arc length of AD in respect to what we know about the circle.
so, arc length of AD is 161° + BA + AD + DC = 360
or getting AD by it self , then
AD =360 -161 -BA -DC
AD = 199°-BA-DC
maybe that's all you need to do, also i'm wondering if there is some more info about this problem , maybe at the top of the page? of off the screen?

Answer:
What happens to an exoskeleton when an arthropod grows? The exoskeleton does not grow or expand, so it is shed and a new larger one grows. This is called molting. ... The process of shedding an outgrown exoskeleton.
Step-by-step explanation:
Answer:
As the body underneath the exoskeleton grows, the animal begins to outgrow its tough exterior. In order to cope with this situation, arthropods undergo a process of shedding their exoskeleton and forming a new one periodically throughout their lifetime.

Cierto tipo de mezcla contiene 5kg de arena y 3 kg de cemento: un constructor necesita 12 toneladas de esta mezcla. ¿qué cantidad se necesita de arena y de cemento?
Answers
Answer:
the sand and cement needed is 7.5 kg and 4.5 kg respectively
Step-by-step explanation:
The computation of the sand and cement needed is shown below:
Given that
The mix of sand and cement is 5kg and 3kg i.e. its ratio is 5:3
And there is a 12kg of mix of both things
So individually it required
For sand = 12 × 5 ÷ 8
= 7.5 kg
For cement = 12 × 3 ÷ 8
= 4.5 kg
Hence, the sand and cement needed is 7.5 kg and 4.5 kg respectively

Answer:

65-50= ∠2
15°=∠2
Step-by-step explanation:
Answer:
d. 15 degrees
Step-by-step explanation:
You're basically trying to find angle DBC. Adding 115 and 50 will give you 165. This means that angle DBC must be 15, as the angles have to add up to 180. Angle 2 and angle DBC are equal, so angle 2 is 15 degrees.

Answers
Answer:
x = − 3
Step-by-step explanation:
Let's solve your equation step-by-step.
− 2x − 4 = x + 5
Step 1: Subtract x from both sides.
− 2x − 4 − x = x + 5 − x
− 3x − 4 = 5
Step 2: Add 4 to both sides.
− 3x − 4 + 4 = 5 + 4
−3x = 9
Step 3: Divide both sides by -3.
−3x / −3 = 9 / −3
x = − 3

Answers
Answer:
For the first part of 4 questions wrong: he would get 42 points
For the second part 48 points
Step-by-step explanation:
For the first part of 4 questions wrong: he would get 42 points because 50 divided by 2 is 25 and 25 minus 4 is 21 and 21 times 2 is 42.
For the last part I'm guessing x = 1 so again 50 divided by 2 is 25 and 25 minus 1 is 24 and 24 times 2 is 48
I think it is right.

33 1/3%=100/3%
A percent as a decimal is percentage divided by 100
(100/3)/100=1/3
Since 1/3 of a number is 24 we can say
n/3=24
n=72
So 24 is 33 1/3% of 72
Intercepts:
Write the ordered pair describing the coordinates of each intercept.
1. x-intercept: -6 2. y-intercept: -2.3 3. y-intercept: 3/4
Find the x-intercept and y-intercept for the graph of each equation.
4. y = 3x – 9 5. y = 5x + 10 6. y=1/2 x+4
7. y = 12 – 6x 8. 2y = -6x + 8
Use the x-intercept and y-intercept to graph each equation.
9. y=-1/2 x-3 10. y = 2x + 4

y-intercept: ______ y-intercept: ______
Graph your answers from #4 and #8 from above.
11. y = 3x – 9 12. 2y = -6x + 8
Answers
The y-intercept is the point where the function crosses the y axis at x=0
1. It is an x-intercept, so y = 0. The ordered pair would be (-6, 0)
2. It is a y-intercept, so x = 0. The ordered pair would be (0, -2.3)
3. It is a y-intercept, so x=0. The ordered pair would be (0, 3/4)
To find the x-intercept, set y = 0. To find the y-intercept, set x=0
4. y-intercept: y = 3(0) -9. y = -9 The y-intercept is at (0, -9)
x-intercept: 0 = 3x -9. 9 = 3x. x = 3. The x-intercept is at (3, 0)
5. x intercept: 0 = 5x +10. -10 = 5x. x = -2. The x-intercept is at (-2, 0)
y-intercept: y = 5(0) + 10. y = 10. The y-intercept is at (0, 10)
If you look at finding the y-intercepts in the two problems above, you may see there is a pattern forming. The y-intercept is the number that your adding or subtracting that is located after the x (ex. y = 4x - 2 - the y-intercept would be -2)
9. First, find the x and y-intercepts. The y intercept is -3 You’d graph that at (0, -3). 0 = -1/2x - 3. -1/2x = 3. x = -6 so the x-intercept is at (-6, 0). If you only need to graph 2 points, then you can graph just those two points and draw a line between them.
To graph y=-1/2x + 3, start at the y-intercept and use the slope (-1/2) to find other points. Because your slope is -1/2, you’d go down 1 unit and then to the right 2 units. That would be your next point. If you wanted your line to go further up, go up one unit and then to the left 2 units. That would be your next point.
